Prices and pack sizes are taken from what was stated in the video transcript. Some items may vary by retailer and time.

Per-battery prices as stated in the transcript (multi-pack totals converted to per-piece where possible).

Battery analyzer drained each non-rechargeable cell at ~300 mA (0.3A) and reported total capacity. Lithium AAs dramatically outperformed alkaline AAs in this test.

Internal resistance was read out for each cell. Lower resistance generally helps under higher current draw.

Lithium AAs were much lighter than alkaline AAs in the video measurements.

Tester set to ~1.25A and voltage was compared across brands. Duracell led the alkalines; a lithium entry reached ~1.27V as well in the transcript.

All batteries were chilled for several hours, then re-tested under ~1.25A load. The top cold performers in the transcript were lithium cells (Energizer Ultimate Lithium highest).
